He has an easy-going personality, but when it comes down to his job as a producer he can become really serious. Despite his job, he is known to sexually harass those whom he finds attractive. This is the primary reason why Ryouma greatly dislikes him, revealing how he endured such harassment from him and why he no longer wished to work with him again.
Jin also attempted to force himself onto Izumi upon meeting him and even wanted to take advantage of Rei (when he was in an emotionally vulnerable state following Izumi and Ryouma falling off the cliff in the manga). However, when Shougo arrived in order to see Rei (who had called him about the matter) and Jin noticed that the two appeared to be romantically involved, he reacted in mere disappointment.
